To all whom it mag concern:

- Be it known that I, J OHN F. OCoxnon, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Antit'ric'tion Side Bearings for Railway-Cars, of which the following is a specification. Y

My invention relates to anti-friction side bearings for railway cars.

Heretofore considerable objection and difficulty have been experienced in the practical construction and use of anti-friction side he rings for railway cars owing to the fact tl but a very limited travel can be secured between the upper and lower bearings or members without unduly increasing the total vertical thickness or height of the anti-friction bearing, as the available spa'ce between the body and truck bolsters of the side bearing is necessarily of small extent owing to other conditions of car construction and to the necessity of keeping the load as low as practicable.

The object of my invention is to tn'ovide an anti-friction side bear-ingot a strong, simple, efficientand durable construction which will permit of any desired amount of antifriction travel of the bolsters in respect to each other, and which at the same time may be easily kept within the available space or vertical height which may be taken up by the side bearing without interfering with tion.

My invention consists in the means I cmploy to n'act-ically accomplish this object or result. That is to say it consists, in connection with the upper bearing plate, secured to the body bolster and the lower bearing plate secured to the truck bolster, of a substantially horizontal but slightly inclined anti-friction or rotary circular disk, having a spherical or substantially spherical upper bearing faceof large curvature engaging the. lower face of the upper bearing plate which is secured to the body bolster, said rotary circular disk being interposed between the upper and lower bearing members. a plurality of radially arranged conical rollers interposed between the anti-friction spherimember which is provided with an annular;

spacing spider having outwardly flaring radial arms extending between adjacent conical rollers. I

My invention consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.

In the accompanying drawing forming a part of this specification, Figure l is an elevation showing the body and truck bolsters of a car having anti-friction side bearings embodying my invention. Fig. 2 is a plan view with the body bolster removed. Fig. 3 is a detail plan view with the upper bearing plate removed. Fig. 4 is a detail vertical section on line 4% of Fig. 2. Fig. 5 is a detail vertical section taken transversely to one of the conical rollers. bottom view of the upper bearing member which is secured to the body bolster.

In the drawing, A represents the truck bolster and B the body bolster ofa railway car; G is the upper bearing plate or member of my side bearing, the same being rigidly secured to the body bolster; D is the lower bearing idly secured to the truck bolster by bolts 4. The lower bearing member I) has an an ular tread or race (Z to receive the small conical rollers F which are interposed between the lower bearing plate and the axially inclined rotary spherically faced anti-friction disk G which is interposed between the upper and lower bearing plates C D. This inclined anti-friction circular disk G has a substanti ally spherical upper bearing face 9 of large curvature and the disk rotates on an axis which is slightly inclined to the vertical so that the line oi' conta'ct between the disk G and the upper bearing member C will be substantially horizontal, as will bereadily understood from Figs. 1. and 4c of the drawing. The anti-friction spherical inclined disk G rotatably combined with or mounted upon the lower bearing member D by means of an integral shaft or stud g on the disk G which tits in a hole (l in the bearing plate I) and is confined'by a key 9 inserted through the stud or shaft gt. The anti-friction circular disk Gr is furnished with an annular conical race or trend 9 on its lower face to. receive the conical rollers F.

plate or member which is rig-v The anti-friction circular disk is fury rushed with an annular flange g which sur- Fig. 6 is a detail upper bearin C as indicated in dotted lines roundsand embraces the corresponding annular flange d on the lower bearing plate D, these interengaging flanges additionally looking or rotatably securing the anti-friction disk G and bearing plate D together, and serving to relieve the pivot stud g from undue severe strains and alsoto exclude dirt and cinders from the anti-friction bearing.

H is a roller spacing device or spider interposed between the lower bearingplate D and the anti-friction disk G and having a plurality of outwardly flaring radial arms it, one for each roller F fitting between adjacent rollers. These outwardly fiaring radial arms h preferably have each two conically curved bearing faces 7L1 corresponding to the curvature of the conical rollers between which they fit. The radial arms h preferably have straight or flat bearing faces 7L2 ,h at their lower portions or at the part which projects below the aXes of the rollers F.

As the pivot or axis g of the anti-friction 'disk G is inclined. from the vertical, the

smaller cone-faced race or tread thereon and the corresponding annular cone-faced tread on the lower bearing plate 1), it will be understood, are slightly tipped or inclined in respect to the horizontal, The spider H has a hub 72? surrounding the pivot or stud g to keep the spider in place. The radial arms, of the spider H serve to keep the con ical rollers in true radial arrangement.

The center about which the spherical bearing face 9 of the disk G is struck should be vertically in line with the center line of the This application is filedas a continuation of my original application, Serial No. 329,971, filed August 10th, 1906, continued as SerialNo. 406,649, filed December 16, 1907, the said applications having becomeabandoned'.
